| 摘 要： | 利用静态颗粒特性实验仪研究了不同堆构条件下颗粒柱有效质量的涨落.发现当只有一种颗粒堆构时涨落随着颗粒柱与颗粒的直径比的增大而减小,除此之外,当有不同颗粒堆构时涨落还随着不同大小颗粒的堆构位置而变化,可将这种现象的机理归结为颗粒柱中的颗粒数量的异同以及颗粒柱与限界之间摩擦力方向的不确定性.

| Abstract: | The fluctuations of the effective mass of particle columns under different heap were studied using static particles device.When there was only one heap structure,the fluctuation reduced with the increase of the diameter ratio of particle column and particle.But when multi heap structures presented,the fluctuation changed with the location of the different heap structures.This phenomenon was caused by the variation of particle quantity in different particle columns and the uncertainty of the direction of fri... |
